KESSLER COOLMOTION®
10 ■ KESSLER SPINDLE TECHNOLOGY
KESSLER is the innovation engine behind state-of-the-art direct drive
technology and is renowned for powerful and energy-efficient motors with
high torque density and top reliability even in high-demand applications.
Practically-based simulations and individual customer calculations are a
prerequisite for the development excellence of KESSLER motors.
The inverter-optimized COOLMOTION® motors are recognized for their
low-loss design and enhanced heat dissipation. Innovative modifications
to the motor components have enabled us to reduce the rotor and
stator losses by 25%. Special construction measures have resulted in
significantly enhanced heat dissipation.
The COOLMOTION® technology optimizes efficiency to a maximum.
{{ achieves a very high torque density
{{ achieves very short acceleration times
